<p>PURPOSE:To effectively use a display picture frame, and to improve an operatability for interaction movement by reducing and moving automatically a window, the using frequency per unit time of which is low and is not used presently for the interaction. CONSTITUTION:A window interaction frequency measuring part 3 measures a interaction frequency per unit time, and an interaction window discriminating part 4 discriminates the window, in which the interaction is held presently (having interaction light). A window control deciding part 8 decides either to reduce and move the respective window or not on the basis of the interaction frequency per unit time of the respective window in a window interaction frequency storing part 5 and the window having the interaction right in an interaction window storing part 6. A window display controlling part 10 controls a window displaying part 2 to reduce and move the window which is decided to be reduced and moved by the window control deciding part 8, to a size and a position, calculated by a window size and position calculating part 9. Thus, the effective use of the display picture frame and the improvement of the operability at the time of moving interaction, can be realized.</p> |
